Hi Paul,
It has been a while, I hope all is well with you. I retired 4 years ago so my trips to the UK will be less frequent but will be for pleasure rather than work!
The document we regularly refer to for connector care is available from Keysight, part number is 08510-90064 and is a free download. See also the Microwaves101.com section on connector care for a condensed table of connector torque requirements.?

Hi Steve it has been a long time since we have spoken

Regarding maximum torque I recently read about the torque requirements but unfortunately I cannot find the article? it defined the
Torque settings for SMA , 3.5 , 2.92,alao 2.4 , 1.85 and they were not all the same?
?
Do you or anyone have the Torque settings for the above connectors
?

Gauging of connectors was mandatory in our metrology labs, as was use of a calibrated torque wrench for the connections. In the event we had to mate SMA to 3.5 mm, 3.5 to 2.92, etc. (any connection that was between mateable but ?non identical connector types) the maximum torque was limited to 5 lb/in to prevent damage to the precision connectors.?

Or male SMA to female 3.5 mm probably.? ?SMA was originally designed to be inexpensive, and the center pin protrusion is not well controlled.? ?I've heard of people using connector gauges to check protrusion before mating,? but I haven't tried it myself.? ?HTH.? ? ? Jim Ford

?It is not just generic cheap SMA connectors. Mini circuits SMA plugs have been known to ruin 2.92mm jacks. Avoid connecting ANY SMA males to 2.92mm females.
